To all whom it may concern: 7

Be it known that I, ALBERT H. Srsson, a citizen of the United States, residlng at High Point, in the county of Guilford and structions in general has for its particular object the provision of an improved cushioning device in connection with a sash rail and stiffening lining of such shape and in such relation that they cooperate to effect a firm rigid construction and one in which the parts are readily assembled and securely held. Other advantages from the standpoint of mechanical construction and operation will be apparent to those skilled in this art.

In order that the invention may be readily understood a practical embodiment of the same is set forth in the accompanying drawing and in the description based thereon. As the invention is also capable of embodiment in other and varied constructional forms the drawings and description are to be construed as illustrative and not in an unnecessarily limiting sense.

In the drawing:

Figure 1 is a front elevation of one form of sash corner and cushion shown in assembled relation to the window frame which is partially broken away;

Fig. 2 is a vertical section through the sash looking toward the lock;

Fig. 3 is a horizontal section taken on the line 33 of Fig. 1; and

Fig. 4 is a fragmentary view in vertical section showing a modified form of cushion strip. 1

Having reference particularly to Figs. 1 to 3 inclusive thesash rail 11 and stile 12 are shown as mitered at 13 and connected to form a sash corner. The sash members 11 and 12 arehere shown as formed of sheet metal tubular in cross section havin a reentrant portion 14 forming a groove or the reception of glass 15 with suitable interposed packing 16. It is desirable both from the standpoint of economy of material and also to encroach as little. as possible upon the window opening that the rail and stile be as narrow as is consistent with strength and with the necessity of afiording a propersuptionI am enabled to reduce the width of the rail and stile to an inch or less and also to employ lighter material for thesame.

In carrying out the inventioniI provide a lock plate 17 which is secured to the rail and stile advantageously by screws 18 extending through into a corner reinforcement hereafter described. This lock plate is angular in outline and preferably L-shaped, one leg extending longitudinally of each of the sash members for a considerable distance beyond the corner of the sash thus bridging the mitered joint between the members. The inner edges of the plate are deflected laterally toward the glass as indicated at 19 and fit snugly against the inner edges of both the rail and stile. The vertical leg of the plate also preferably has formed integral therewith by stamping a lift 20 which projects into the glass area of the sash. It will be observed that the outer edges of the lock plate l7do not extend to the outer edges of the rail and stile but are sufiiciently remote therefrom to clear the stop 21 and the sill 22 thus presenting for engagement with the stop and sill a plane surface throughout and nothrequiring the lock plate to be inset in the sas The snug fit of the deflected portions 19 of the lock plate Over the inner edges of the sash members tends to efi'ect a firm engagement of the parts thus materially assisting and relieving the screws 18 from undue strain. This'result is further enhanced by the provision of a stud 23 formed integral with and projecting from the lock plate into prises a finger piece 27 projecting adjacent the lift and also an angular plunger or extension 28 terminating in a hook nose 29 recess so as to force the sash in the opposite direction and prevent rattling. In order to safe-guard the pivot screw 26 against turn ing a pin 33 is seated within the plate 17 and projects inwardly therefrom into engagement with the slot of the screw.

The lower edge of the rail 11 is provided -with a reentrant dove-tail groove 34: adapted to receive a correspondingly shaped clip 35 having seated therein a rubber cushioning strip36 which bears upon the window sill '37 to prevent the entrance of the elements underneath the sash.

In order to provide a particularly rigid and efficient connection between the rail and stile at each corner of the sash and to strengthen the'rail carrying the cushion a reinforcing lining 38 is provided which is L-shaped in side elevation and substantially U-shaped in cross section, the U opening in wardly. The limbs of the U are curved in wardly at their extremities, as indicated at 39, so as to follow the inward curvature of the sash members into the restricted space at each side of the glazing roove and terminating with their edges a utting against the walls of said groove as clearly shown in the drawing. Heretofore it has not been usual to have the reinforcement extend into this space on each side of the glazing groove and the lateral strength of the reinforcement has been correspondingly limited.

That portion of the reinforcement 38 which extends into the lower rail to any desired extent is slotted asindicated in Figs. 2 and 4:, so as to embrace the dove-tail groove 34 and the clip 35, the relative positlon of the two walls of the reinforcement being maintained by a spacing bolt 10 extending transversely and rigidly joining the two walls.

Not 'only does the reinforcing lining 38 stifien the side and edge walls of the rails and stiles, but byareason of its extending into the space on each side of the glazing groove and also embracing the dove-tail groove within which the cushion strip is same along the lower side where it sustains the shocks incident to closing of the window.

The clip 35 having been permanently clamped upon the correspondingly shaped tongue 42 of the cushion 37 is assembled with the sash rail 11 by sliding the same longitudinally of the groove from the corner of the sash. The end of the clip may be slightly deformed as by springing the same outward to bind within the groove and prevent further sliding movement, or a drop of solder or other expedient may be employed for this purpose, although in practice no tendency to shift is mani ested and no precautionary steps are found necessary to be taken.

The form of the lower face of the cushion may be convex in cross section as in Fig. 2 or concave as in Fig. 4, but in either case I find the dovetail tongue and groove connection between the cushion and sash by means of the dovetail clips of great advantage and a distinct advance in the art.

I claim;

'1. In sheet metal sash construction, the combination with a hollow sash rail, and a cushion on the bottom thereof, of an interior reinforcing lining having its lower edge abutting the lower wall to vertically support the same against blows transmitted through the cushion.

2. In sheet metal sash construction, the combination with a hollow sash rail having a groove formed in its lower face, and a cushion on the bottom thereof seated in the groove, of an interior reinforcing lining laterally supporting the side walls and extending into the space at the side of the groove to vertically support the lower'wall of the sash against blows transmitted through the cushion.-

3. In sheet metal sash construction, the combination with a rail and stile connected to form a sash corner and provided along izo rior angular reinforcement U-shaped in cross section with the limbs extending into the space on each side of the groove, the rail having along its bottom a dove-tail groove, a dove-tail slide within the groove, and a cushion seated within the slide, the bottom of the U-shaped reinforcement cut away to accommodate the cushion groove and the lower, edges of the reinforcement extending into the space on each side of the rentrant walls of the cushion groove and interlocking therewith, substantially as described.

5. In sheet metal sash construction, the

combination with a rail and stile connected to form a sash corner and provided along their inner edges with a groove, of aninterior angular reinforcement U-shaped in cross section with the limbs extending into the space on each side of the groove, the

' rail having along its bottom a dove-tail groove, a dove-tail slide within the groove, and a cushion'seated within theslide, the

. bottom of the U-shaped'reinforcement out described. 7

6. The combination with a sash member having in its'edge a reentrant-groove, and a resilient cushion seated within tlIG gIIOOVG, of a reinforcing member disposed within the sash and having portions supporting the outer walls of the sash and also extending into the space alongside the reentrant groove whereby to laterally support the walls forming the cushion seat, substantially as described. v

7. The combination with a sash member having in its lower edge a reentrant dovetail groove, and a resilient cushion seated within the groove, of a reinforcing member disposed within the sash and supporting the side. walls of the sash and having portions extending. along the lower wall into the space alongside the rentrant groove whereby to laterally support the walls forming the cushion seat, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses.
